Power system balancing for deep decarbonization of the electricity sector

We explore the oper­a­tions, bal­anc­ing require­ments, and costs of the West­ern Elec­tric­ity Coor­di­nat­ing Coun­cil power sys­tem under a strin­gent green­house gas emis­sion reduc­tion tar­get. We include sen­si­tiv­i­ties for tech­nol­ogy costs and avail­abil­ity, fuel prices and emis­sions, and demand pro­file. Meet­ing an emis­sions tar­get of 85% below 1990 lev­els is fea­si­ble across a range of assump­tions, but the cost of achiev­ing the goal and the tech­nol­ogy mix are uncer­tain. Deploy­ment of solar pho­to­voltaics is the main dri­ver of stor­age deploy­ment: the diur­nal peri­od­ic­ity of solar energy avail­abil­ity results in oppor­tu­ni­ties for daily arbi­trage that stor­age tech­nolo­gies with sev­eral hours of dura­tion are well suited to pro­vide. Wind out­put exhibits sea­sonal vari­a­tions and requires stor­age with a large energy sub­com­po­nent to avoid cur­tail­ment. The com­bi­na­tion of low-​​cost solar tech­nol­ogy and advanced bat­tery tech­nol­ogy can pro­vide sub­stan­tial sav­ings through 2050, greatly mit­i­gat­ing the cost of cli­mate change mit­i­ga­tion. Pol­icy goals for stor­age deploy­ment should be based on the func­tion stor­age will play on the grid and there­fore incor­po­rate both the power rat­ing and dura­tion of the stor­age sys­tem. These goals should be set as part of over­all port­fo­lio devel­op­ment, as sys­tem flex­i­bil­ity needs will vary with the grid mix.

Daniel L. Sanchez is an alumni of the Energy and Resources Group and the Renew­able and Appro­pri­ate Energy Lab­o­ra­tory at the Uni­ver­sity of California-​​Berkeley. He is inter­ested in quan­ti­ta­tive analy­sis to inform pub­lic pol­icy, focus­ing on bioen­ergy and cli­mate pol­icy. His cur­rent research focused design, deploy­ment, and com­mer­cial­iza­tion of bioen­ergy with car­bon cap­ture and seques­tra­tion (BECCS) tech­nolo­gies. Daniel has pre­vi­ously held posi­tions with the Advanced Research Projects Agency-​​Energy (ARPA-​​E), Green for All, and the Cal­i­for­nia Pub­lic Util­i­ties Com­mis­sion. He holds an M.S. in Energy and Resources and a B.S.E. in Chem­i­cal and Bio­mol­e­c­u­lar Engi­neer­ing from the Uni­ver­sity of Pennsylvania.

Dan has been a post-​​doctoral fel­low at the Carnegie Insti­tu­tion at Stan­ford Uni­ver­sity, and is cur­rently a AAAS Fel­low in Wash­ing­ton, DC.  He is inter­ested in the deploy­ment and com­mer­cial­iza­tion of tech­nolo­gies that sig­nif­i­cantly reduce energy-​​related CO2 emis­sions or remove CO2 from the atmos­phere. Daniel’s work and engage­ment spans the aca­d­e­mic, non­govern­men­tal, and gov­ern­men­tal sec­tors. He recently com­pleted a post­doc­toral research fel­low­ship with the Carnegie Insti­tu­tion for Sci­ence work­ing with Drs. Chris Field and Katharine Mach. Daniel has pre­vi­ously held posi­tions with the Advanced Research Projects Agency-​​Energy (ARPA-​​E), Green for All, and the Cal­i­for­nia Pub­lic Util­i­ties Commission.

He holds a Ph.D. and M.S. from the Energy and Resources Group at the Uni­ver­sity of California-​​Berkeley, and a B.S.E. in Chem­i­cal and Bio­mol­e­c­u­lar Engi­neer­ing from the Uni­ver­sity of Pennsylvania.

Hildalgo-​​Gonzalez, Patricia

Patri­cia grad­u­ated as an indus­trial and elec­tri­cal engi­neer in 2012 from Pon­ti­f­i­cia Uni­ver­si­dad Católica de Chile (PUC). Dur­ing her under­grad­u­ate stud­ies she worked as a Lin­ear Alge­bra teach­ing assis­tant for three years, per­formed research in Dr. Daniel Kammen’s Renew­able and Appro­pri­ate Energy Lab­o­ra­tory (RAEL) at UC Berke­ley work­ing on the SWITCH model for the US. She also worked (funded by CONICYT) on solar energy research at the Uni­ver­sity of Ari­zona (under­grad the­sis). Once she grad­u­ated she worked as a Lin­ear Alge­bra lec­turer at PUC. Later on, for over a year and a half she worked as a research assis­tant at UC Berke­ley and at the Nat­ural Resources Defense Coun­cil (per­form­ing SWITCH-​​Chile research). Her top­ics of inter­est are how to highly inte­grate renew­able energy in the grid, long-​​term power sys­tem plan­ning, sto­chas­tic load dis­patch mod­els, energy pol­icy, and energy economics.

Ponce de Leon, Diego

I am work­ing on my  MS/​PhD at the Energy and Resources Group (ERG). My research is in low-​​carbon (low-​​impact) energy sys­tems and eco­nomic devel­op­ment, mod­el­ing high renew­able energy future sce­nar­ios, and deploy­ing sMArt Grid (high-​​tech/​low-​​cost) pilots in the ris­ing south.  I’ve worked in Chi­a­pas (Mex­ico) devel­op­ing regional micro­cre­dit schemes and river sur­vey stud­ies,  designed and built ‘low-​​tech/​high– impact’ water dis­tri­b­u­tion sys­tems for small com­mu­ni­ties in Uganda and Hon­duras, have used GIS mod­els and InVest (Inte­grated Val­u­a­tion of Envi­ron­men­tal ser­vices and Trade­offs) to study the hydrol­ogy of the Linthipe Basin (Malawi), and inves­ti­gated link­ages between hydro­log­i­cal vari­abil­ity, energy use, and agri­cul­ture in Pun­jab and Telan­gana (India).

My cur­rent work is in Nicaragua devel­op­ing and build­ing sce­nar­ios for the SWITCH model – opti­miz­ing the pen­e­tra­tion of renew­able energy into the country’s elec­tric power sys­tem, and deploy­ing the country’s first micro-​​scale demand response pro­gram (DR) through the use of ‘flex­i­ble energy toolkits’.
